The Book of Leviticus is weird - let's fix it!! 

God's presence is good: how can it be dangerous? Sun - both good and dangerous

3 solutions: Rituals, Priesthood, and Purity rules

Ritual - a lot of animal sacrifices: Thank you and I am sorry

Priesthood: being directly in God's presence is dangerous

Purity laws: clean vs. unclean; pure vs. impure - cannot be close to God in a impure state!

Random rules? Not really random: Skin diseases - Israelites associate with life and death

Impure - not wrong or sinful, is inappropriate into God's presence while impure

16-17: Day of Atonement - the priest would take two goats: one killed and the other scapegoat
